Can a 440 volt single phase device be made to run on 220 volt single phase?

Not directly. You could use a 220V - 440V transformer to boost the voltage up to 440. Be sure its rated for the proper KW. Check the nameplate on the device for the KW rating. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicator
to insure the circuit is, in fact, de-energized.

How can you get a 240V single-phase power from a 120V 3-phase service?
First of all there is no common three phase 120 volt service. There is in North America a three wire 120/240 volt single phase service. That being said, if you want to change a 120 volt source to 240 volts it must be done with a transformer. Its classification is a step up transformer. The primary side of the transformer H1 - H2 will be connected to the 120 volts. The secondary side of the transformer X1 - X2 will be connected to the 240 volt load. The transformer is sized by the current required by the 240 volt load.
Does a 480 volt panel have a neutral bus?
Usually yes. A typical 480 volt panel is a 3 phase panel with 480 volts line-to-line and 277 volts line-to-neutral. However, I did once see a panel that was 480 volts, 3 phase, but because it served only motors it did not have a neutral. (a 3 phase motor doesn't use a neutral.) Similarly, if a panel uses only 2 legs of a 3 phase 480 volt system, which would be called single phase, it would not require a neutral if it only feeds 480 volt single phase loads. But I find the idea of no neutral to be extremely unusual and in my one personal experience, I blamed it on the age of the system. In 16 years of commercial and industrial construction I have never installed a 3 phase panel without a neutral and all my work is designed by engineers.
What size wire and breaker for a 240 volt single phase 20 kw electric furnace rated at 83.3 amps?
AWG #3 copper.
What is the minimum voltage of US household mains supply?
240, single phase for houses208 3 phase for comerical property, can be single phase.480 volt for industrial property or 660 volts,all 60 HzUSA calls it single phase but there is actually 2 hot leads coming into the house with a natural and a ground.It is actually two 120 volt 'hots' which are 180° out of phase from each other. Voltage between either of these and ground will be 120 V. Voltage between the two hots is 240 volts. It is single phase because it is pulled off one of the phases from 3-phase, then a center tapped transformer gives the two 'opposite phases' (ground/neutral is off the center tap)In Vietnam we have 440 volts, 3 phase, 50 Hz on the poles.They bring in one hot wire and one ground. I call this single phase,It equals 220 volts in your house.
How do you get 380 volt from 220 3 phase?
Only with a 3 phase transformer.
Can you wire up a 240 volt single phase water heater to 277 volt single phase?
no
In a 240 volt single phase circuit A phase is 4000 watts B phase is 7000 watts what is the neutral load?
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
Is there a single phase 460 volt variable speed control?
No you need a Roto Phase
Can a 230 volt single phase watt hour meter be used to monitor 115 volt single phase?
Yes it would work pretty well but it might not meet its accuracy specification.
What is the ac equivalent of 98v DC?
120 volt single phase rectifies to about 96 volt DC
How do you get a 220 volt single phase from 380 volt 3phase synchrounos generator?
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
How do you change a 3 phase 440 volt motor to a 3 phase 220 volt motor?
You can not change it. 440 volt is by design. However you run it with 220 single phase supply, but it would run far lower power.
What transformer do you need if you have primary voltage of 600 3 phase and require 240 volt 1 phase?
A single phase 600 to 240 Volt transformer using two phases of the three phase primary.
Can you use 240 volt 3 phase to run a machine that is 240 volt single phase?
Yes, if the motor is rated 240 volts 3 phase.There is such a thing as 240 volt 3 phase power.However if you are asking if you can use 240 volts single phase on a three phase motor, then the answer is no.
How do you get single phase 440 from three phase 440?
You Don't. 440volt 3-phase is actually 480 volts, taking a single phase gives 277Volts single phase. To get single phase 440 you would use one leg of three phase 440/760 three phase power.
Does a 2 horsepower rotary converter plug into 120 single phase and convert it to plug in a 3 phase outlet?
All my experience with rotary phase converters have been in converting 240 volt single phase into 240 volt three phase. They all were hard wired into their respective systems, so my answer is no.
What is the voltage for a single phase from a 415 volt 3 phase and neutral supply?
240V. 415 / 1.73 = 240
